Abstract

Das rohrförmige Ventilgehäuse eines 4/3-Wegeventils besitzt an seiner Längsseite einen mittigen Rücklaufanschluß zu einem Vorratsbehälter für Hydraulikflüssigkeit, links und rechts vom Rücklaufanschluß liegen symmetrisch dazu je ein Arbeitsanschluß zur Vorder- bzw. Rückseite eines Hydraulik­ kolbens sowie je ein Pumpenanschluß zu einer mit konstan­ tem Druck fördernden Pumpe. Diese Hydraulikanschlüsse sind durch zwei mit dazwischenliegender Schraubenfeder gegenläufig arbeitenden Steuerkolben steuerbar, deren Stirnseiten durch elektromagnetisch betätigte Vorsteuerven­ tile mit Pumpendruck beaufschlagbar sind. Das bei Links­ bzw. Rechtslauf des Hydraulikkolbens an der einen Kolben­ seite verdrängte Volumen der Hydraulikflüssigkeit gelangt über die beiden Arbeitsanschlüsse zur anderen Kolbenseite.
